The name sounds alarming, but ringworm has nothing to do with worms. It is a common fungal infection that affects the skin, scalp, or nails. Despite how easily it spreads, it is usually harmless and can be treated effectively with the right care.
What exactly is ringworm?
Ringworm is caused by a group of fungi known as dermatophytes. These fungi thrive in warm and moist environments and can live on the skin, hair, and nails. The infection often appears as a red, circular rash with clearer skin in the centre, giving it a ring-like appearance.
It can occur on different parts of the body and may be referred to by different names. For instance, when it affects the feet, it is called athlete’s foot, and when it appears in the groin area, it is known as jock itch.
How it spreads
Ringworm is highly contagious and spreads through direct contact. This may happen when you touch an infected person, share personal items such as towels or combs, or come into contact with contaminated surfaces. It can also spread from animals, especially pets like cats and dogs.
Poor hygiene, sweating, and crowded living conditions can increase the risk of infection.
Signs to look out for
The symptoms of ringworm can vary depending on the area affected, but common signs include:
-A red, scaly rash that may be itchy
-A ring-shaped pattern on the skin
-Cracked or peeling skin
–Hair loss in patches when it affects the scalp
-Thickened or discoloured nails in more severe cases
If left untreated, the infection may spread to other parts of the body or to other people.
How to treat ringworm
Treatment for ringworm is usually straightforward, especially when it is detected early.
Use antifungal creams
Most cases can be treated with over-the-counter antifungal creams or ointments. These should be applied directly to the affected area for at least two to four weeks, even if the rash begins to clear earlier.
Keep the area clean and dry
Fungi thrive in moisture, so it is important to wash the affected area regularly and dry it thoroughly. Avoid tight clothing that may trap sweat.
Avoid sharing personal items
Do not share towels, clothing, or bedding until the infection has completely cleared. Wash these items frequently to prevent reinfection.
Treat infected pets
If you suspect your pet may be the source, seek advice from a veterinarian and ensure the animal receives proper treatment.
Oral medication when necessary
In more severe cases, especially when the scalp or nails are affected, a doctor may prescribe oral antifungal medication. This is often required when topical treatments are not effective.
Preventing future infections
Preventing ringworm is largely about maintaining good hygiene and being mindful of shared spaces. Simple steps can go a long way:
-Keep your skin clean and dry
-Wear breathable fabrics, especially in hot weather
-Use protective footwear in public showers or swimming areas
-Avoid close contact with infected individuals or animals
-Wash your hands regularly
When to see a doctor
While most cases can be treated at home, you should seek medical advice if the infection does not improve after a few weeks, spreads rapidly, or affects the scalp or nails. Children and individuals with weakened immune systems may also require closer medical attention.
